AbstractThe aim of this study is to investigate the effect of nitration and nitrox process on wear performances of tool steels. For this purpose, samples were seperated as two categories. One group was exposed to nitration process in salt bath at 530 0C during 6 hours. For other group, nitrox process was applied at 4900C during 2 hours after nitration. Reciprocating wear test was performed for all specimens under the loads of 10N, 20N and 40N according to the ASTM G99 standard. Microstructures and worn surfaces of specimens were analysed using Scanning Electron Microscope (SEM). Results show that, wear performances of specimens exhibit difference when they are exposed nitration and oxidation process. And also they show better performance under the lower loads.
